It's the simple words and simple imagery that make the poem incredible. Even the fact that you make mention of "trinkets and Toothbrushes" items that one would otherwise not really give much notice of or exclude to add something more intimate.

The last paragraph is what snares me the most. Mainly because even as you read it, you almost feel the sigh as yourself turn off the lights. You've captured the right mood for the poem and you keep it up right up to the end.
